1 Technical Specification Sheet Document No A June 24th, 2010 Laboratory Room Single Duct Supply Air Terminal Features Figure 1. Laboratory Room Single Duct Supply Air Terminal. The APOGEE Automation Laboratory Room Single Duct Supply Air Terminal is an industrial-grade, easyto-install pre-packaged airflow measurement and control terminal unit. The Laboratory Room Single Duct Supply Air Terminal is a round inlet, rectangular outlet, one piece insulated and lined terminal that provides cooling only or cooling with hot water reheat. When used with the Laboratory Room Controller, it provides fast acting, stable and precise laboratory supply airflow control over the entire range of room airflow requirements. Measurement of airflow is accomplished by four quadrant sensing technology to achieve measurement accuracy of 3% of actual flow (sensor only). Airflow control is achieved utilizing a round single blade damper mounted on a zinc plated steel shaft with polyethylene bushings and mechanical stops. Construction is 22 gauge-galvanized steel, including the casing and damper. Eight standard sizes with airflow capacities from 35 to 8530 cfm - others are available. Four quadrant airflow sensor with multi-point, center averaging and signal amplification. Low radiated and discharge sound levels. ARI-certified sound performance ratings. 22 gauge casing with slip and drive discharge connection. Solid zinc plated steel damper shaft on self lubricating polyethylene bushings for fast acting control and maintenance free operation. Low non-recoverable static pressure loss. Round, beaded inlet collar accepts nominal flexible or rigid duct (size 18 has rectangular inlet). Internal insulation 3/4-inch fiber-free foam which meets requirements of NFPA 90A and UL181. Closed cell structure foam allows for disinfecting and hand washing with detergents and water. Meets mechanical standards UL 181, NFPA 90A, ASTM E84, UL 723 and bacteria standard ASTM C665. Ultra-low leakage, damper and casing. Up to four rows of hot water reheat coils. Description The Single Duct Supply Terminal consists of the following components (refer to Figures 2 through 6). Galvanized steel round inlet duct, damper blade in sizes from 4 (10.1 cm) to 16 (40.6 cm) diameter; size 18 unit has a rectangular inlet and two 16 (40.6 cm) diameter dampers. Four quadrant airflow measurement sensor Rectangular, lined and insulated casing with slip and drive outlet connections. Factory-mounted controls options. Pneumatic or electronic damper control.
